Description

Technical Field

[0001] This utility model relates to the field of sleeve production technology, specifically to a pushing and anti-jamming device. Background Technology

[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction, and as chain-like objects used to obstruct traffic passages (such as in streets, river or harbor entrances). They are also chains used for mechanical transmission. A chain generally consists of five basic components: inner chain plate, pin, roller, bushing, and outer chain plate. The quality of a chain mainly depends on the pin and bushing.

[0003] Currently, sleeve rolling is carried out on sleeve rolling machines. Existing sleeve rolling machines typically include a U-shaped rolling device, an O-shaped rolling device, and a pushing device. The U-shaped rolling device cuts the strip steel and bends the cut strip steel into a U-shape. Then, the pushing device pushes the U-shaped strip steel to the O-shaped rolling device to wrap it into an O-shape, thus completing the sleeve rolling.

[0004] In the above solution, the existing U-shaped coiling device is prone to deviation in the bending position during the process of bending the strip into a U-shape. This can cause the pushing device to jam during the process of pushing the U-shaped strip, thus preventing it from continuing to bend the strip into a U-shape. At this time, the sleeve coiling machine is still operating normally, which will cause a large amount of strip to be damaged. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pushing and anti-jamming device. By providing a pushing rod, a linkage component and an anti-jamming component, it can ensure that if the bending position deviates, the chain sleeve winding machine can be controlled to stop running. This solves the problem in the prior art that the chain sleeve winding machine is still running normally after the bending position deviates, thus ensuring that a large amount of strip steel is not damaged.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A pushing and anti-jamming device includes a chain sleeve winding machine. The chain sleeve winding machine includes a machine body, a lifting frame, a feeding device, a winding device, and a driving device. A guide component is provided on the side wall of the machine body. A support plate is provided on the guide component. A movable push rod and a linkage component are provided on the side wall of the support plate. An anti-jamming component is provided at the end of the push rod.

[0008] When a sleeve needs to be made, the feeding device is activated to transport the strip steel into the coiling device. Then, the drive device is activated to move the lifting frame downwards, thereby cutting the strip steel and bending the cut strip steel into a U-shape. At the same time, the linkage component is activated, which moves the support plate to the left. The leftward movement of the support plate moves the push rod to the left, ensuring that the push rod does not interfere with the coiling operation of the coiling device. Then, the lifting frame is controlled to reset, and the linkage component moves the support plate to the right. The rightward movement of the support plate moves the push rod to the right, thus pushing the U-shaped strip steel to the required position. If the bending position is deviated, and the push rod cannot push the U-shaped strip steel to move, the push rod will be blocked by the U-shaped strip steel and move to the left. This will activate the anti-jamming component, which controls the clutch of the chain sleeve coiling machine to stop working, thus stopping the chain sleeve coiling machine and ensuring that a large amount of strip steel is not damaged.

[0009] By incorporating a push rod, a linkage component, and an anti-jamming component, the chain sleeve winding machine can be stopped if the bending position deviates. This solves the problem in existing technologies where the chain sleeve winding machine continues to operate normally after the bending position deviates, thus ensuring that a large amount of strip steel is not damaged.

[0010] The utility model is further configured such that: the guide assembly includes two guide rods symmetrically inserted into the side wall of the machine body, and the support plate is simultaneously fixed to the ends of the two guide rods.

[0011] The above technical solution can guide the support plate, preventing it from tilting or vibrating when moving.

[0012] The utility model is further configured such that: the movable push rod includes a damping ring fixed in the support plate, and the push rod is inserted into the damping ring.

[0013] With the above technical solution, if the bending position deviates and the push rod cannot push the U-shaped strip to move, while the support plate is still moving normally to the right, the push rod will be blocked by the U-shaped strip and move to the left after overcoming the resistance of the damping ring, thereby activating the anti-jamming component.

[0014] The utility model is further configured such that: the linkage component includes two support rods symmetrically inserted into the side wall of the support plate, the protruding ends of the support rods passing through the support plate and fixed to the side wall of the machine body, the support rods are provided with compression springs, one end of the compression springs is fixed to the end of the support rods, the other end of the compression springs is fixed to the upper end of the support plate, a guide shaft is rotatably connected to the side wall of the machine body, and a chain is fixed to the lower end of the lifting frame, the chain is fixed to the side wall of the support plate through the protruding end of the guide shaft.

[0015] With the above technical solution, when the lifting frame moves upward, it also drives the chain to move upward, which in turn pulls the support plate to the right and stretches the compression spring. When the lifting plate moves downward, the chain stops pulling the support plate, causing the compression spring to reset. The reset of the compression spring causes the support plate to reset, which in turn drives the support plate to move to the left.

[0016] The utility model is further configured such that: the anti-jamming component includes a stop bar fixed to the end of the push rod, a snap-fit ​​rod fixed to the side wall of the support rod, a linkage rod inserted into the snap-fit ​​rod, an abutment rod fixed to the clutch pedal of the chain sleeve winding machine, and the lower end of the linkage rod pressing against the upper end of the abutment rod.

[0017] With the above technical solution, when the linkage rod presses against the upper end of the abutment rod, the clutch of the chain sleeve winding machine is engaged, thus making the chain sleeve winding machine run. If the bending position deviates and the push rod cannot push the U-shaped strip to move, while the support plate is still moving normally to the right, the push rod will be blocked by the U-shaped strip and move to the left after overcoming the resistance of the damping ring. At the same time, it will drive the stop rod to move to the left. The leftward movement of the stop rod pushes the linkage rod and the locking rod to disengage, causing the linkage rod to disengage from the abutment rod, thereby disengaging the clutch and stopping the chain sleeve winding machine.

[0018] The beneficial effects of this utility model are:

[0019] Compared with existing technologies, by incorporating a push rod, a linkage component, and an anti-jamming component, the chain sleeve winding machine can be stopped if the bending position deviates. This solves the problem in existing technologies where the chain sleeve winding machine continues to operate normally after the bending position deviates, thus ensuring that a large amount of strip steel is not damaged.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] The following is for reference Figures 1 to 2 This utility model will now be described.

[0025] A pushing and anti-jamming device includes a chain sleeve winding machine. The chain sleeve winding machine includes a machine body 1, a lifting frame 2, a feeding device 3, a winding device 4, and a driving device 5. A guide component is provided on the side wall of the machine body 1, and a support plate 6 is provided on the guide component. A movable pushing rod 7 and a linkage component are provided on the side wall of the support plate 6, and an anti-jamming component is provided at the end of the pushing rod 7.

[0026] When a sleeve needs to be made, the feeding device 3 is started to transport the strip steel into the coiling device 4. Then, the drive device 5 is started to move the lifting frame 2 downward, thereby cutting the steel strip and bending the cut strip steel into a U-shape. At the same time, the linkage component is activated, which moves the support plate 6 to the left. The leftward movement of the support plate 6 moves the push rod 7 to the left, ensuring that the push rod 7 does not interfere with the coiling operation of the coiling device 4. Then, the lifting frame 2 is reset, and the linkage component moves the support plate 6 to the right. The rightward movement of the support plate 6 moves the push rod 7 to the right, thereby pushing the U-shaped strip steel to the required position. If the bending position is deviated, and the push rod 7 cannot push the U-shaped strip steel to move, the push rod 7 will be blocked by the U-shaped strip steel and move to the left. This will activate the anti-jamming component, which controls the clutch of the chain sleeve coiling machine to stop working, thus stopping the chain sleeve coiling machine and ensuring that a large amount of strip steel is not damaged.

[0027] By incorporating a push rod 7, a linkage component, and an anti-jamming component, the chain sleeve winding machine can be stopped if the bending position deviates. This solves the problem in the prior art where the chain sleeve winding machine continues to operate normally after the bending position deviates, thus ensuring that a large amount of strip steel is not damaged.

[0028] The guide assembly includes two guide rods 8 symmetrically inserted into the side wall of the body 1, and a support plate 6 is fixed to the ends of the two guide rods 8.

[0029] The support plate 6 can be guided to prevent it from tilting or vibrating when it moves.

[0030] The movable push rod 7 includes a damping ring 9 fixed inside the support plate 6, and the push rod 7 is inserted into the damping ring 9.

[0031] If the bending position deviates and the push rod 7 cannot push the U-shaped strip to move, while the support plate 6 is still moving normally to the right, the push rod 7 will be blocked by the U-shaped strip and move to the left after overcoming the resistance of the damping ring 9, thus activating the anti-jamming component.

[0032] The linkage assembly includes two support rods 10 symmetrically inserted into the side wall of the support plate 6. The extended ends of the support rods 10 through the support plate 6 are fixed to the side wall of the machine body 1. A compression spring 11 is provided on the support rod 10. One end of the compression spring 11 is fixed to the end of the support rod 10, and the other end of the compression spring 11 is fixed to the upper end of the support plate 6. A guide shaft 12 is rotatably connected to the side wall of the machine body 1. A chain 13 is fixed to the lower end of the lifting frame 2. The chain 13 is fixed to the side wall of the support plate 6 through the extended end of the guide shaft 12.

[0033] When the lifting frame 2 moves upward, it also drives the chain 13 to move upward, which in turn pulls the support plate 6 to the right and stretches the compression spring 11. When the lifting plate moves downward, the chain 13 stops pulling the support plate 6, which causes the compression spring 11 to reset. The reset of the compression spring 11 causes the support plate 6 to reset, which in turn causes the support plate 6 to move to the left.

[0034] The anti-jamming component includes a stop bar 14 fixed to the end of the push rod 7, a snap-fit ​​rod 15 fixed to the side wall of the support rod 10, a linkage rod 16 inserted into the snap-fit ​​rod 15, and an abutment rod 17 fixed to the clutch pedal of the chain sleeve winding machine, with the lower end of the linkage rod 16 pressing against the upper end of the abutment rod 17.

[0035] When the linkage rod 16 presses against the upper end of the abutment rod 17, the clutch of the chain sleeve winding machine is engaged, thus putting the chain sleeve winding machine into operation. If the bending position deviates, and the push rod 7 cannot push the U-shaped strip to move, while the support plate 6 is still moving normally to the right, the push rod 7 will be blocked by the U-shaped strip and move to the left after overcoming the resistance of the damping ring 9. At the same time, it will drive the stop rod 14 to move to the left. The leftward movement of the stop rod 14 pushes the linkage rod 16 to disengage from the locking rod 15, causing the linkage rod 16 to disengage from the abutment rod 17, thereby disengaging the clutch and stopping the chain sleeve winding machine.

[0036] Working principle:

[0037] When a sleeve needs to be made, the feeding device 3 is activated to transport the strip steel into the coiling device 4. Then, the drive device 5 is activated to move the lifting frame 2 downward, thereby cutting the strip steel and bending the cut strip steel into a U-shape. At the same time, the chain 13 stops pulling the support plate 6, causing the compression spring 11 to reset. The reset of the compression spring 11 drives the support plate 6 to reset, thereby moving the support plate 6 to the left. The leftward movement of the support plate 6 drives the push rod 7 to the left, ensuring that the push rod 7 does not interfere with the coiling operation of the coiling device 4. Then, the lifting frame 2 is controlled to reset, and the chain 13 is moved upward, thereby pulling the support plate 6 to the right. The rightward movement of the support plate 6 drives the push rod 7 to the right, thereby pushing the U-shaped strip steel to the required position. The position simultaneously causes the compression spring 11 to stretch. When the linkage rod 16 presses against the upper end of the abutment rod 17, the clutch of the chain sleeve winding machine is engaged, thus making the chain sleeve winding machine run. If the bending position deviates, and the push rod 7 cannot push the U-shaped strip steel to move, while the support plate 6 is still moving normally to the right, the push rod 7 will be blocked by the U-shaped strip steel and move to the left after overcoming the resistance of the damping ring 9. At the same time, it will drive the stop rod 14 to move to the left. The stop rod 14 moves to the left and pushes the linkage rod 16 to disengage from the locking rod 15, causing the linkage rod 16 to disengage from the abutment rod 17, thereby disengaging the clutch and stopping the chain sleeve winding machine, thus ensuring that a large amount of strip steel is not damaged.

[0038] Simultaneously, the support plate 6 is moved to the right by the linkage component. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principle of this utility model. These improvements and modifications assumed above should also be considered within the protection scope of this utility model.
